-; Test that functions with dynamic allocas get inlined in a case where
-; naively inlining it would result in a miscompilation.
-; Functions with dynamic allocas can only be inlined into functions that
-; already have dynamic allocas.

-; FIXME: This test is xfailed because the inline cost rewrite disabled *all*
-; inlining of functions which contain a dynamic alloca. It should be re-enabled
-; once that functionality is restored.
